Putting in aragonite sand in the tank will turn it eventually into a live sand bed anyways
This is good because if you get sand sifters, like some gobies, sand stars, etc., they'll need a good live sand bed to stay healthy & well-fed. I have a yellow watchman & twin spot gobies & I love watching them sift the sand for me. You'll also want to keep it at only 1 or 2" deep (at least that seems to be the recommended depth nowadays). I too don't like the look of a bare bottom, but I know many other reefers (especially SPS lovers) swear by bb.
